Bombardier Movia CR151

The tender for trains under the contract R151 was closed on 4 September 2017 with 5 bids. The LTA had shortlisted all of them and the tender results were published.[7]

The CR151 trains are the second batch of trains that are not manufactured by Kawasaki and the past consortiums, after the C651 trains which were manufactured by Siemens.

It will feature a new livery of green and red stripes against a white background running around the cars, similar to the C151C. It is also the first train to feature a massive redesign over the other previous rolling stock, including the sixth rolling stock, C151C. That includes a more streamlined body design with a unique headlight placement and also the first batch of trains to come with bright white LED headlights over the conventional fluorescent yellow lights.

The trains also include several unique features, such as condition monitoring sensors and analytic systems to detect faults beforehand as well as an onboard self-test system that checks whether the train is fit for operation. In addition, four trains will also have an automatic track inspection system, consisting of cameras, lasers and sensors, to detect rail defects.

Furthermore, the trains would also have wider areas near the doors to aid the movement of passengers in and out of the train, and tip-up seats that cater to parents with prams, wheelchair users and people with personal mobility devices or foldable bicycles without reducing seat count.[9][10]

The trains will also utilise a Bombardier Mitrac propulsion and control system.[2]

It will be the second train type to feature LTA's new passenger information display, similar to those of the CT251 trains, during manufacturing process in which it will consists of a single, elongated LCD screen displaying the travel information, such as the upcoming stations the train will arrive at, door closing warnings and attractions nearby the station.

On 1 April 2019, Bombardier Transportation and the Land Transport Authority launched a mockup of the interior of the CR151 at the SG Mobility Gallery at LTA's office at Hampshire Road.[11] A poll was conducted to gather public opinion on the features of the train such as the livery, interior colour scheme, the tip-up seats and the Additional Passenger Media Display (APMD).[12]
